It does not traverse or at least I ran into the same issue. Never could
figure out what should really happen. 

If you look at the patch I submitted for the @DefaultProperty issue, I had
to traverse to find the default property, which is often 1 or 2 levels up
from the subclass that the client implements.

It may be time to create yet another AnnotationUtils static helper class.

Subject: Re: Component names inside the containers

I actually started prototyping this last night. I ran into what appears to
be a bug in Class#getAnnotation(), but I'm not sure. The Javadoc for this
method isn't specific, but the Javadoc for getDeclaredAnnotations() implies
that getAnnotation() and getAnnotations() will traverse the class hierarchy
looking for annotations, but getDeclaredAnnotations() will not. However, I
have not found that to be the case in practice. I can walk up the class
hierarchy myself, but I'm wondering if I'm simply misunderstanding
something. Any ideas?

necessary, but it is nice to have and obviously has some use cases. Also, I
believe Spring offers a similar feature via the BeanNameAware interface, so
it would be nice to have a comparable feature.
